Abstract

On-demand cloud-oriented content delivery service provision is the challenging task for the most of researchers. Antecedent end users used to request to the central server for accessing information but now a day's massive use of mobile devices upshots delivery of intended contents virtually from edge servers which are scattered over the earth surface. Thus, placing content effectively to appropriate edge servers and searching it from edge servers are two big issues for cloud-oriented content delivery network providers (CCDNPs). To solve these issues, at first we have clustered all edge servers using voronoi diagram to locate each edge server into a particular voronoi cell and also search the requested content from nearest edge server of the requested user current location using Delaunay triangulation over our aforementioned clustering technique. Consequently we have also used binary item-to-item collaborative filtering for placing content based upon the users' interest. Our proposed content searching technique and replica placement strategy not only solve the users' requirement but also overcome the open challenges of the CCDNPs.
基于voronoi的面向云的内容分发网络中,一种基于二进制项对项协同过滤的副本放置策略
面向云的按需内容交付服务的提供对大多数研究人员来说是一项具有挑战性的任务。以前,终端用户习惯于向中央服务器请求访问信息,但现在,移动设备的大量使用导致了预期内容几乎从分散在地球表面的边缘服务器交付。因此,将内容有效地放置到适当的边缘服务器并从边缘服务器搜索内容是面向云的内容交付网络提供商(CCDNPs)面临的两大问题。为了解决这些问题,我们首先使用voronoi图对所有边缘服务器进行集群,将每个边缘服务器定位到特定的voronoi单元中,并在前面提到的集群技术上使用Delaunay三角测量从请求用户当前位置的最近边缘服务器搜索请求的内容。因此,我们还使用二元项目到项目协同过滤来根据用户的兴趣放置内容。我们提出的内容搜索技术和副本放置策略不仅解决了用户的需求,而且克服了CCDNPs的开放性挑战。
